RouterOS Scripts

RouterOS is the operating system developed by MikroTik for networking tasks. This repository holds a number of scripts to manage RouterOS devices or extend their functionality.

Use at your own risk, pay attention to license and warranty!

Requirements

Latest version of the scripts require recent RouterOS to function properly. Make sure to install latest updates before you begin.

Specific scripts may require even newer RouterOS version.

Initial setup

Get me ready!

If you know how things work just copy and paste the initial commands. Remember to edit and rerun global-config-overlay! First time users should take the long way below.

Live presentation

Want to see it in action? I've had a presentation Repository based RouterOS script distribution including demonstation recorded live at MUM Europe 2019 in Vienna.

⚠️ Warning: Some details changed. So see the presentation, then follow the steps below for up-to-date commands.

The long way in detail

The update script does server certificate verification, so first step is to download the certificates. If you intend to download the scripts from a different location (for example from github.com) install the corresponding certificate chain.

/ tool fetch "https://git.eworm.de/cgit/routeros-scripts/plain/certs/ISRG-Root-X2.pem" dst-path="isrg-root-x2.pem";

Note that the commands above do not verify server certificate, so if you want to be safe download with your workstations's browser and transfer the files to your MikroTik device.

ISRG Root X2

Then we import the certificates.

/ certificate import file-name=isrg-root-x2.pem passphrase="";

For basic verification we rename the certificate and print the count. Make sure the certificate count is one.

/ certificate set name="ISRG-Root-X2" [ find where common-name="ISRG Root X2" ];
/ certificate print count-only where fingerprint="69729b8e15a86efc177a57afb7171dfc64add28c2fca8cf1507e34453ccb1470";

Always make sure there are no certificates installed you do not know or want!

All following commands will verify the server certificate. For validity the certificate's lifetime is checked with local time, so make sure the device's date and time is set correctly!

Now let's download the main scripts and add them in configuration on the fly.

:foreach Script in={ "global-config"; "global-config-overlay"; "global-functions" } do={ / system script add name=$Script source=([ / tool fetch check-certificate=yes-without-crl ("https://git.eworm.de/cgit/routeros-scripts/plain/" . $Script . "\?h=routeros-v6") output=user as-value]->"data"); };

screenshot: import scripts

The configuration needs to be tweaked for your needs. Edit global-config-overlay, copy configuration from global-config (the one without -overlay). Save changes and exit with Ctrl-o.

/ system script edit global-config-overlay source;

And finally load configuration and functions and add the scheduler.

/ system script { run global-config; run global-functions; };
/ system scheduler add name="global-scripts" start-time=startup on-event="/ system script { run global-config; run global-functions; }";

The last step is optional: Add this scheduler only if you want the scripts to be updated automatically!

/ system scheduler add name="ScriptInstallUpdate" start-time=startup interval=1d on-event=":global ScriptInstallUpdate; \$ScriptInstallUpdate;";

Changes for RouterOS v6

Let's consider RouterOS v6 being legacy. If you want to stay with RouterOS v6 for some time add these lines to your global-config-overlay, if missing:

# Use branch routeros-v6 with RouterOS v6:
:global ScriptUpdatesUrlSuffix "\?h=routeros-v6";

Then reload the configuration.

Changes for RouterOS v7

RouterOS v7 is the future, and default branch main expects it. Just drop $ScriptUpdatesUrlSuffix from your global-config-overlay to use that.

Then reload the configuration and continue below to update scripts.

Updating scripts

To update existing scripts just run function $ScriptInstallUpdate. If everything is up-to-date it will not produce any output.

$ScriptInstallUpdate;

Adding a script

To add a script from the repository run function $ScriptInstallUpdate with a comma separated list of script names.

$ScriptInstallUpdate check-certificates,check-routeros-update;

screenshot: install scripts

Scheduler and events

Most scripts are designed to run regularly from scheduler. We just added check-routeros-update, so let's run it every hour to make sure not to miss an update.

/ system scheduler add name="check-routeros-update" interval=1h on-event="/ system script run check-routeros-update;";

screenshot: schedule script

Some events can run a script. If you want your DHCP hostnames to be available in DNS use dhcp-to-dns with the events from dhcp server. For a regular cleanup add a scheduler entry.

$ScriptInstallUpdate dhcp-to-dns,lease-script;
/ ip dhcp-server set lease-script=lease-script [ find ];
/ system scheduler add name="dhcp-to-dns" interval=5m on-event="/ system script run dhcp-to-dns;";

There's much more to explore... Have fun!

Installing custom scripts & modules

My scripts cover a lot of use cases, but you may have your own ones. You can still use my scripts to manage and deploy yours, by specifying base-url (and url-suffix) for each script.

This will fetch and install a script hello-world.rsc from the given url:

$ScriptInstallUpdate hello-world.rsc "base-url=https://git.eworm.de/cgit/routeros-scripts/plain/README.d/"

screenshot: install custom script

(Yes, the example url still belongs to the repository for easy handling - but the url can be what ever you use.)

For a script to be considered valid it has to begin with a magic token. Have a look at any script and copy the first line without modification.

Starting a script's name with mod/ makes it a module and it is run automatically by global-functions.
